Using version 13.2 and referencing .NET Standard 2.1 class library and annotating with a NotNullAttribute results in error when compiling with linking on.

Steps to Reproduce

  1. Create .NET Standard class library, choosing .NET Standard 2.1
  2. Link from iOS project
  3. Set linking to sdk or all
  4. Build

Expected Behavior

Project compiles successfully

Actual Behavior

MTOUCH : error MT2101: Can't resolve the reference 'System.Void System.Diagnostics.CodeAnalysis.NotNullAttribute::.ctor()', referenced from the method 'System.Void TestLib.Check::NotNull(System.Object)' in 'netstandard, Version=2.1.0.0, Culture=neutral, PublicKeyToken=cc7b13ffcd2ddd51'.

Discovered by this XI customer issue: xamarin/xamarin-macios#7087

It looks like we didn't fully update with the latest NS2.1 API additions as part of #11430.

I ran a API comparison on dotnet/standard against the Xamarin.iOS 13.0 stable release and it shows these missing members:

The EditorBrowsableAttribute entries don't really affect us, but the rest does.

Yeah, that's a serious issue. Some CodeAnalysis attributes are compiler referenced all the time with C#8

Yeah we are missing changes from dotnet/standard#1349 (Jul 18 2019) and few more. EditorBrowsableAttribute is a noise (it can be ignored in the diff tool via a special parameter)

@akoeplinger, @marek-safar, @EgorBo - thanks for the quick investigation

Any idea on when a fix might be released?

This breaks all sorts of stuff - for example, using Entity Framework 3.0 - and presumable any other libraries that are producing .NET Standard 2.1 assemblies referencing nullable attributes -

Error MT2101: Can't resolve the reference 'System.Void System.Diagnostics.CodeAnalysis.DoesNotReturnIfAttribute::.ctor(System.Boolean)', referenced from the method 'System.Void Microsoft.EntityFrameworkCore.Utilities.Check::DebugAssert(System.Boolean,System.String)' in 'netstandard, Version=2.1.0.0, Culture=neutral, PublicKeyToken=cc7b13ffcd2ddd51'.

Great - thanks

I can confirm that Xamarin iOS 13.2.0.47 fixes the problem I was seeing - I can successfully build and test apps referencing the nullable reference types attributes in .NET Standard 2.1 with linking enabled.

When is the service release expected?

We expect the servicing release to happen first half of this week for Xamarin.iOS and Mac.

What is the status of this? How do you use .NET Standard 2.1 with Mono or Xamarin? This comment on this issue indicates that you can't use .NET Standard with Mono: dotnet/standard#1689 (comment)
